mmc: tegra: add basic Tegra186 support

2016-05-31T18:22:59Z

Tegra186's MMC controller needs to be explicitly identified. Add another compatible value for it. Tegra186 will use an entirely different clock/reset control mechanism to existing chips, and will use standard clock/reset APIs rather than the existing Tegra-specific custom APIs. The driver support for that isn't ready yet, so simply disable all clock/reset usage if compiling for Tegra186. This must happen at compile time rather than run-time since the custom APIs won't even be compiled in on Tegra186. In the long term, the plan would be to convert the existing custom APIs to standard APIs and get rid of the ifdefs completely. The system's main eMMC will work without any clock/reset support, since the firmware will have already initialized the controller in order to load U-Boot. Hence the driver is useful even in this apparently crippled state. Signed-off-by: Stephen Warren Signed-off-by: Tom Warren

ARM: tegra: use DT bindings for GPIO naming

2016-05-31T16:53:56Z

There are currently many places that define the list of all Tegra GPIOs; the DT binding header and custom Tegra-specific header file gpio.h. Fix the redundancy by replacing everything with the DT binding header file. Signed-off-by: Stephen Warren Reviewed-by: Simon Glass Signed-off-by: Tom Warren

ARM: tegra: enable GPU node by compatible value

2016-05-04T20:31:03Z

In current Linux kernel Tegra DT files, 64-bit addresses are represented in unit addresses as a pair of comma-separated 32-bit values. Apparently this is no longer the correct representation for simple busses, and the unit address should be represented as a single 64-bit value. If this is changed in the DTs, arm/arm/mach-tegra/board2.c:ft_system_setup() will no longer be able to find and enable the GPU node, since it looks up the node by name. Fix that function to enable nodes based on their compatible value rather than their node name. This will work no matter what the node name is, i.e for DTs both before and after any rename operation.

tegra: video: Clean up the old LCD/PWM driver code

2016-02-16T16:17:53Z

Remove the old PWM code. Remove calls to CONFIG_LCD functions now that we are using driver model for video. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

tegra: lcd: Merge tegra124-lcd.c into display.c

2016-02-16T16:17:51Z

There isn't a lot of benefit of have two separate files. With driver model the code needs to be in the same driver, so it's better to have it in the same file. Signed-off-by: Simon Glass Acked-by: Anatolij Gustschin Signed-off-by: Tom Warren

tegra: pwm: Add a driver for the tegra PWM

2016-02-16T16:17:50Z

This PWM supports four channels. The driver always uses the 32KHz clock, and adjusts the duty cycle accordingly. Signed-off-by: Simon Glass Signed-off-by: Tom Warren

Add more SPDX-License-Identifier tags

2016-01-19T13:31:21Z

In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini

ARM: tegra: rename GPU functions

ARM: tegra: Implement clk_m

2015-09-16T23:10:22Z

On currently supported SoCs, clk_m always runs at the same frequency as the oscillator input. However newer SoC generations such as Tegra210 no longer have that restriction. Prepare for that by separating clk_m from the oscillator clock and allow SoC code to override the clk_m rate. Signed-off-by: Thierry Reding Signed-off-by: Tom Warren
