| * | | | MIPS: ath79: add TP-Link WDR4300 board supportOleksij Rempel2017-08-157-0/+243
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This provides low level initialization of pll and ddr2. Resulting binary should work from SRAM, DDR2 and SPI flash. If started from DDR2 RAM level initialization will skipped.

| * | | clk: imx: cpu: don't store the address of a function parameterUwe Kleine-König2017-08-151-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function imx_clk_cpu takes a const char *parent_name as second paramter. The implementation introduced in commit 9a89ed9d281e then uses the address of this function parameter to assign clk.parent_names. This is an address on the stack that is saved in the clk tree and of course this is easily overwritten by later execution paths of barebox. Without this fix the clk_dump command reproducibly crashes on i.MX7 (which is the only SoC that makes use of imx_clk_cpu()).

Needs to adjust clock names as the clock names used in the device tree does not match the clocknames used in platform_data. The clocknames in the device tree are not unique, so it was not an option to rename the clocks.

To support this the syntax for lcd_wiring_mode was extended to include this info. This is an extension compared to the documented bindings, and an extension the kernel does not support (yet). The binding documents that there can be more than one gpio to power on/off the display but current implmentation supports only one gpio. There are no users that requires more than one gpio so this is good enough. The clk name used for hclk differs from device trees and platform data. We could rename the clocl used in platform data but the name "hclk" is not unique. Configure clockname based on configuration method.

Move registration of the GPIO to the driver so we no longer need to duplicate this for each board. As an intended side-effect there is no longer any references to platform_data outside atmel_lcdc_register() so remove it from struct atmel_lcdfb_info The implementation assumes that GPIO=0 is the same as no power control. This prevents us from using any GPIO=0 for power control, but this is not considered a problem for current users. Future DT users will not have this limitation. This commit include a fix so we will actually power down if requested. Previously this was hardcoded to ON.
