| | | | | | | | | | | Add function to parse FIMD data from device tree. The driver still supports non-DT case. Define panel_info statically in some file if you are not using DT. If you have defined DT node for FIMD, panel_info will be filled using the bindings of FIMD DT node.

| * mmc:sdhci:fix: Change default interrupts enabled at SDHCI initializationŁukasz Majewski2013-03-12-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes sdhci_init()'s behavior to NOT enable all interrupt sources by default. Moreover interrupt signaling has been disabled. This patch do not enable interrupts which aren't served in u-boot (they are defined at sdhci.h but NOT used elsewhere): - SDHCI_INT_CARD_INSERT, SDHCI_INT_CARD_REMOVE, SDHCI_BUS_POWER, SDHCI_INT_CARD_REMOVE, SDHCI_INT_CARD_INT Special care shall be put on SDHCI_INT_CARD_INT, which indicates interrupt generated by SD card. According to "SD Host Controller Simplified Spec. ver 3.00" when bit 8 (Card Interrupt Status Enable) at "Normal Interrupt Status Enable Register" (offset 0x34) is set, the card interrupt detection is started. Then eMMC card may cause the SD controller to set this bit and then this interrupt is passed to booted OS and might cause kernel crash. To sum up: - Only enable interrupts, which are served at u-boot - This cleanup as a side effect fixes SDHCI's CARD INTERRUPT problem at Linux kernel (versions 3.6+, sdhci controller) - Keep masked bits at "Normal Interrupt Signal Enable Register" (0x38h) Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Cc: Lei Wen <leiwen@marvell.com> Cc: Andy Fleming <afleming@freescale.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>

Workarounds are implemented for: * Register writes can't be too close to each-other in time, or they will be lost. * Register accesses must all be 32-bit, so implement custom accessors. This code was extracted from: git://github.com/gonzoua/u-boot-pi.git master which was created by Oleksandr Tymoshenko. Portions of the code there were obviously based on the Linux kernel at: git://github.com/raspberrypi/linux.git rpi-3.6.y commit f5b930b "Main bcm2708 linux port" signed-off-by Dom Cobley. swarren changed the following for upstream: * Removed hack udelay()s in bcm2835_sdhci_raw_writel(); setting SDHCI_QUIRK_WAIT_SEND_CMD appears to solve the issues. * Remove register logging from read*/write* functions. * Sort out confusion with min/max_freq values passed to add_sdhci(). * Use more descriptive variable names and calculations in IO accessors. * Simplified and commented twoticks_delay calculation. * checkpatch fixes.

| | * | Tegra: I2C: Add T114 clock support to tegra_i2c driverTom Warren2013-03-14-5/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | T114 has a slightly different I2C clock, with a new (extra) divisor in standard/fast mode and HS mode. Tested on my Dalmore, and the I2C clock is 100KHz +/- 3Hz on my Saleae Logic analyzer. Added a new entry in compat_names for T114 I2C since it differs from the previous Tegra SoCs. A flag is set when T114 I2C HW is found so new features like the extra clock divisor can be used. Signed-off-by: Tom Warren <twarren@nvidia.com> Acked-by: Laxman Dewangan <ldewangan@nvidia.com>
