From 166097e8775343898cab84f1f23b4aacb35783db Mon Sep 17 00:00:00 2001 From: Thomas Abraham Date: Sat, 23 Apr 2016 22:18:09 +0530 Subject: clk: exynos: add clock driver for Exynos7420 Soc Add a clock driver for Exynos7420 SoC. There are about 25 clock controller blocks in Exynos7420 out of which support for topc, top0 and peric1 blocks are added in this initial version of the driver.

This involves changes to the EDP and FIMD (frame buffer) drivers. Existing PWM, simple-panel and pwm-backlight drivers are used. These work without additional configuration since they use the device tree settings in the same way as Linux. Boards converted are: - snow - spring - peach-pit - peach-pi All have been tested. Not converted: - MIPI display driver - s5pc210_universal - smdk5420 - smdk5250 - trats - trats2 Signed-off-by: Simon Glass Acked-by: Anatolij Gustschin Signed-off-by: Minkyu Kang --- arch/arm/mach-exynos/include/mach/dp_info.h | 1 + board/samsung/common/board.c | 15 - configs/peach-pi_defconfig | 4 + configs/peach-pit_defconfig | 4 + configs/snow_defconfig | 4 + configs/spring_defconfig | 4 + drivers/video/exynos/exynos_dp.c | 146 ++++++++-- drivers/video/exynos/exynos_fb.c | 407 ++++++++++++++++------------ drivers/video/simple_panel.c | 2 + include/configs/exynos5-common.h | 1 - include/configs/exynos5-dt-common.h | 5 +- 11 files changed, 377 insertions(+), 216 deletions(-) (limited to 'include') diff --git a/arch/arm/mach-exynos/include/mach/dp_info.h b/arch/arm/mach-exynos/include/mach/dp_info.h index 8ce33d64d7f..1079e1ef1e0 100644 --- a/arch/arm/mach-exynos/include/mach/dp_info.h +++ b/arch/arm/mach-exynos/include/mach/dp_info.h @@ -72,6 +72,7 @@ struct exynos_dp_priv { unsigned char dpcd_rev; /*support enhanced frame cap */ unsigned char dpcd_efc; + struct exynos_dp *regs; }; enum analog_power_block { diff --git a/board/samsung/common/board.c b/board/samsung/common/board.c index 799517428db..0eb066ce478 100644 --- a/board/samsung/common/board.c +++ b/board/samsung/common/board.c @@ -158,21 +158,6 @@ int board_early_init_f(void) board_i2c_init(gd->fdt_blob); #endif -#if defined(CONFIG_EXYNOS_FB) - /* - * board_init_f(arch/arm/lib/board.c) calls lcd_setmem() which needs - * panel_info.vl_col, panel_info.vl_row and panel_info.vl_bpix, - * to reserve frame-buffer memory at a very early stage.

The serial driver, serial_s5p.c, is DM-only. This is OK for U-Boot, but in SPL, this will fail with the following compile error: drivers/built-in.o: In function `get_current': ...u-boot/drivers/serial/serial.c:387: undefined reference to `default_serial_console' This warning happens because common/console.c is compiled into U-Boot SPL if CONFIG_SPL_SERIAL_SUPPORT . The common/console.c invokes serial_*() functions and since exynos5 does not use DM in SPL, these functions come from drivers/serial/serial.c . The serial_*() locate default serial port by calling default_serial_console(), but because the serial_s5p.c is DM-only, it does no longer define default_serial_console(). Thus the error.
