* sunxi: video: Use frontend for dma on sun4i to fix memory bandwidth problemsHans de Goede2015-01-22-4/+130
| | | | | | | | | | | | | | | | | | | | Testing has shown that on sun4i the display backend engine does not have deep enough fifo-s causing flickering / tearing in full-hd mode due to fifo underruns. On sun4i use the display frontend engine to do the dma from memory, as the frontend does have deep enough fifo-s. As added advantage of this is that it results in much better memory bandwidth as it reduces the amount of dram bank switches, for more details see: http://ssvb.github.io/2014/11/11/revisiting-fullhd-x11-desktop-performance-of-the-allwinner-a10.html Note that this changes the pipeline searched for in the simplefb node, we can get away with doing this now, since no kernel has yet shipped with simplefb dtb nodes, and I will make sure to get a simplefb node with the new pipeline into 3.19 before it ships.

* video: ssd2828: Allow using 'pclk' as the PLL clock sourceSiarhei Siamashka2015-01-22-7/+28
| | | | | | | | | | | | | | | | | | | Instead of using the internal 'tx_clk' clock source, it is also possible to use the pixel clock signal from the parallel LCD interface ('pclk') as the reference clock for PLL. The 'tx_clk' clock speed may be different on different boards/devices (the allowed range is 8MHz - 30MHz). Which is not very convenient, especially considering the need to know the exact 'tx_clk' clock speed. This clock speed may be difficult to identify without having device schematics and/or accurate documentation/sources every time. Using 'pclk' is free from all these problems.

* video: Add support for SSD2828 (parallel LCD to MIPI bridge)Siarhei Siamashka2015-01-22-0/+616
| | | | | | | | | | | | | | | | | | | SSD2828 can take pixel data coming from a parallel LCD interface and translate it on the fly into MIPI DSI interface for driving a MIPI compatible TFT display. SSD2828 is configured over SPI interface, which may or may not have MISO pin wired up on some hardware. So a write-only SPI mode also has to be supported. The SSD2828 support code is implemented as a utility function and needs to be called from real display drivers, which are responsible for driving parallel LCD hardware in front of the video pipeline. The usage instructions are provided as comments in the header file.

* sunxi: axp221: Add ELDO[1-3] supportSiarhei Siamashka2015-01-22-0/+43
| | | | | | | | | | | | | | | | | | And also add Kconfig option for selecting ELDO3 voltage. The reason for having this option is that the Android kernel sets ELDO3 to 1.2V when powering up LCD in the case if 'lcd_if' configuration variable is set to 6 (LCD_IF_EXT_DSI) in the FEX file. Most likely to supply power for a SSD2828 chip. However on the MSI Primo81 tablet, which is using this particular 'lcd_if = 6' setup for LCD, setting the ELDO3 voltage appears to be unnecessary and it works regardless. Having no schematics of this tablet, I can only guess that 1.2V is supplied to SSD2828 in some other way.

| | | | | | | | | | We do not use the axp209 interrupt, and at least in my mini-x (which does not have a power button) the pwr-button pin and the irq pin are soldered together, so if the axp209 keeps it irq asserted too long it will see a 10s pwr-button press and hard power off the board, disabling the irqs fixes this.

* sunxi: display: Make lcd display clk phase configurableHans de Goede2015-01-22-6/+1
| | | | | | | | | | | | | | | | | | | | While running some tests with an Olinuxino-A13-Micro + a 7" Olimex LCD module I noticed that the screen flickered. This is caused by the lcd display clk phase reg value being set to 0, where it should be 1 in this setup. This commit adds a Kconfig option for the lcd display clk phase, so that we can set it per board. This defaults to 1, because looking at all the fex files in sunxi-boards, that is by far the most used value. This commit updated the Ippo and MSI Primo73 tablet defconfigs to override the default of 1 with 0, as that is the correct value for those tablets, this keeps the register settings the same as before this commit. The Olinuxino-A13 defconfigs are not updated, changing the register setting for these boards from 0 to 1, this is intentional.

| * mmc: Skip changing bus width for MMC cards earlier than version 4.0Andrew Gabbasov2015-01-19-2/+5
| | | | | | | | | | | | | | | | | | | | | | Wider bus widths (larger than default 1 bit) appeared in MMC standard version 4.0. So, for MMC cards of any earlier version trying to change the bus width (including ext_csd comparison) does not make any sense. It may work incorrectly and at least cause unnecessary timeouts. So, just skip the entire bus width related activity for earlier versions. Signed-off-by: Andrew Gabbasov <andrew_gabbasov@mentor.com> Tested-by: Alexey Brodkin <abrodkin@synopsys.com>
| * mmc: Avoid redundant switching to 1-bit bus width for MMC cardsAndrew Gabbasov2015-01-19-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If all the commands switching an MMC card to 4- or 8-bit bus width fail, and the bus width for the controller and the driver is still set to default 1 bit, there is no need to send one more command to switch the card to 1-bit bus width. Also, if the card or host controller do not support wider bus widths, there is no need to send a switch command at all. However, if one of switch commands succeeds, but the subsequent ext_csd fields comparison fails, the card should be switched to some other bus width (next in the list for the loop), or to default 1-bit bus width as a last resort. That's why it would be incorrect to just remove the 1-bit bus width case from the list, it should still be processed in some cases. panto: Minor cosmetic edit removing superfluous parentheses.

| | | | | | | | | | | | | | | | | | The eMMC partition write reliability settings are to be set while partitioning a device, as per the eMMC spec, so changes to these attributes needs to be done in the hardware partitioning API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an API to do hardware partitioning on eMMC devices. The new mmc_hwpart_config() function does the partitioning in one go. As the different attributes and partitioning options on eMMC may be interdependent validation has to be done based on the complete partitioning configuration. The function accepts three modes: - MMC_HWPART_CONF_CHECK: just validates that the configuration is valid. - MMC_HWPART_CONF_SET: validates and sets all the fields in EXT_CSD but without setting the "partitioning completed" bit, and thus is reversible. - MMC_HWPART_CONF_COMPLETE: does everything and is thus not reversible.

| * mmc: the ext_csd data may be used during init even if reading failedDiego Santa Cruz2015-01-19-1/+3
| | | | | | | | | | | | | | | | | | | | The mmc_startup() function uses the ext_csd data even if reading it from the mmc device failed. This bug was introduced in commit bc897b1d4d86597311430dbe7b3e6c807c8c53e5. We now bail out if reading it fails, this should not be a problem as ext_csd was introduced in MMC 4.0 and this code is conditional on MMC >= 4.0.

| * mmc: eMMC partitioning data is not effective till partitioning completedDiego Santa Cruz2015-01-19-23/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC spec says that partitioning is only effective after the PARTITION_SETTING_COMPLETED is set in EXT_CSD (and a power cycle was done, but that we cannot know). Thus the partition sizes and attributes should be ignored when that bit is not set, otherwise the various capacities are not coherent (e.g., the user data capacity will be that of the unpartitioned device while partition sizes would be non-zero). Prescence of non-zero partitioning data is nevertheless still used to activate the high-capacity size definitions (EXT_CSD_ERASE_GROUP_DEF) as it is necessary to set that to write any of the partitioning fields in EXT_CSD, so having partitioning data means someone previously activated that and we should keep it activated.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The eMMC spec mandates that the high-capacity group size definitions should be enabled when the device is partitioned (by setting ERASE_GROUP_DEF in EXT_CSD). The current test to determine when this is required misses a few cases. In particular a device may have been partitioned without setting the enhanced attribute on any partition or partitioning may be completed without creating any extra partitions. This change moves the code to set ERASE_GROUP_DEF to after reading all partition information. It is also enabled when PARTITIONING_SETTING_COMPLETED is set as it is necessary to enable ERASE_GROUP_DEF before setting that bit, so it means that the user previously switched to the high capacity definitions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit fixes a number of issues with the reset sequence of musb-new in host mode: 1) Our usb device probe relies on a second device reset being done after the first descriptors read. Factor the musb reset code into a usb_reset_root_port function (and add this as an empty define for other controllers), and call this when a device has no parent. 2) Just like with normal usb controllers there needs to be a delay after reset, for normal usb controllers, this is handled in hub_port_reset, add a delay to usb_reset_root_port. 3) Sync the musb reset sequence with the upstream kernel, clear all bits of power except bits 4-7, and increase the time reset is asserted to 50 ms. With these fixes an usb keyboard I have now always enumerates properly, where as earlier it would only enumerare properly once every 5 tries. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
