* efikamx: Fix pmic_init() argumentFabio Estevam2013-11-27-1/+1
| | | | | | | | | On efikamx board the PMIC is connected via SPI interface, so it does not make sense to pass I2C_PMIC into the pmic_init() interface. Pass the SPI bus number via CONFIG_FSL_PMIC_BUS option instead. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

* pmic: Extend PMIC framework to support multiple instances of PMIC devicesŁukasz Majewski2012-11-14-3/+9
| | | | | | | | | | | | | | | | | | The PMIC framework has been extended to support multiple instances of the variety of devices responsible for power management. This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB Interface Circuit). Power related includes have been moved to ./include/power directory. This is a first of a series of patches - in the future "pmic" will be replaced with "power". Two important issues: 1. The PMIC needs to be initialized just after malloc is configured 2. It uses list to hold information about available PMIC devices Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Stefano Babic <sbabic@denx.de>

* mxc: Fix SDHC multi-instance clockBenoît Thébaudeau2012-10-16-0/+4
| | | | | | | | | | | | | | | | | | On mxc, each SDHC instance has a dedicated clock, so gd->sdhc_clk is not suitable for the multi-instance use case (initialization made directly with fsl_esdhc_initialize()). This patch fixes this issue by adding a configuration field for the SDHC input clock frequency.

* efikamx: refine USB supportMatt Sealey2012-09-04-8/+13
| | | | | | | | | | | | | | | | | | | | | | | | | Because of the way USB pad settings are handled it doesn't make sense to be able to build the Efika MX board support without CONFIG_CMD_USB turned on. So, we change the build to always compile in USB support. We do not need to check for CONFIG_CMD_USB like we do with CONFIG_MXC_SPI since the USB subsystem will error out of the compile for us. Additionally, the following behaviors have changed; * Smartbook "preboot" should not set input and output to USB keyboard as there is no display support * board_eth_init is implemented such that it does not cause U-Boot to report an explicit failure ("CPU Net Initialization Failed"). Since Ethernet is implemented via USB (fixed on Smarttop, pluggable on Smartbook, and handled by "usb start") - the warning that is left ("No ethernet found") is perfectly reasonable at the point it is printed since the USB system hasn't been started and nothing has been probed yet.

* fsl_esdhc: Remove cache snooping for i.MXBenoît Thébaudeau2012-09-01-2/+2
| | | | | | | | | | | | | | | The cache snooping feature of Freescale's eSDHC IP is not available on i.MX, so disable it globally for this architecture. This avoids setting no_snoop for all i.MX boards, and it prevents setting a reserved bit of a reserved register if fsl_esdhc_mmc_init() is used on i.MX, like in arch/arm/cpu/armv7/imx-common/cpu.c/cpu_mmc_init(). Since no_snoop was only used on i.MX, get rid of it BTW.

* efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's ↵Matt Sealey2012-09-01-25/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | production U-Boot We have no idea where the DCD was derived from for Smartbook support, but they differ from the Smarttop settings, MX51EVK settings and certainly don't correspond to any shipped or development version of U-Boot that Genesi has ever had on any Smartbook. So, copy the calibrated, verified settings from the U-Boot as shipped with every Smartbook since retail production. Remove those few settings that just set the POR defaults which have already been confirmed for the previous Smarttop DCD change. One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks basically don't exist at retail and the number of units in the world is less than 5 (3 of which are at the Genesi office or owned by Genesi employees). Many hours of memory testing confirms the new settings are stable.

* efikamx: update to Efika MX Smarttop and Smartbook boardsMatt Sealey2012-09-01-375/+229
| | | | | | | | | | | | | | | | | | | | | | This is a rework of a previously submitted patchset and bundles the main board support and USB support into a single commit. It requires the patch "mx5: add iomux-mx51.h include" * Use iomux-mx51.h include to simplify board configuration. * Simplify LED support (remove efikamx_toggle_led, change lit LEDs). * Simplify MMC support for CD and WP pin differences. * Fix broken CPU voltage setting - comment said 1.1V but the code set to 1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and all available Linux kernels would drop the voltage to 1.1V anyway and work reliably. This should lower power consumption during the boot process. * Function renames for readability. * Some board identification string changes to match actual product names. * Passes checkpatch (v2) Signed-off-by: Matt Sealey <matt@genesi-usa.com> Cc: Stefano Babic <sbabic@denx.de>
* efikamx: configure Smarttop PCBID and LED pads in DCD for convenienceMatt Sealey2012-09-01-0/+10
| | | | | | | | | | | | | | | | PCBID pads seem to need time to settle due to external pulldowns, otherwise we are reading floating GPIO pins with implicit pad pullups and get the wrong data. However we can't "wait" at the time we need them before relocation, since timers are not available. The time taken to get from DCD to the code requiring the pads set seems to be more than long enough (even with caches enabled). We have space in the DCD due to the DDR settings changes to configure all the pad settings we need for this, plus the LED pad settings too which reduces the amount of code required later on.

* efikamx: remove drive strength function and roll its functionality into the DCDMatt Sealey2012-09-01-101/+18
| | | | | | | | | | | | | | | | | | | Efika MX boards configure their DDR pad settings twice, one in the DCD generated from imximage_*.cfg and again in init_drive_strength called before relocation. Rather than doing this, roll the changes it makes into the DCD so DDR is set up before a single line of code in U-Boot is run. The settings are identical with this DCD block which is shorter (by 7 entries) than the old one, and after the output of init_drive_strength since a lot of the functionality in the existing DCD and init_drive_strength function was just setting the POR defaults. This goes to explain some now-missing entries. Several hundred rounds of mtest have been run to test the settings before and after to confirm DDR is stable and no ill-effects have been found.
