[U-Boot] [PATCH 0/4] EXYNOS5: Add GPIO numbering feature
by Rajeshwari Shinde 20 Nov '12

20 Nov '12

This patchset adds GPIO numbering feature where pinmux setting can be done just by seding the pin munber and we do not have to remember which bank it belongs to. Rajeshwari Shinde (4): EXYNOS5: Add GPIO unique pin numbering support S5P: GPIO: Add GPIO pin numbering to driver EXYNOS5: Enable GPIO Numbering. EXYNOS: Update pinmux to use gpio numbering arch/arm/cpu/armv7/exynos/pinmux.c | 150 ++++++-------- arch/arm/include/asm/arch-exynos/gpio.h | 351 +++++++++++++++++++++++++++++++ drivers/gpio/s5p_gpio.c | 158 +++++++++++++- include/configs/smdk5250.h | 3 + 4 files changed, 569 insertions(+), 93 deletions(-) -- 1.7.4.4

[U-Boot] mx53loco: Fix build error when CONFIG_VIDEO is disabled
by Vikram Narayanan 14 Nov '12

14 Nov '12

The inclusion of LCD patch into mx51evk breaks the build when CONFIG_VIDEO is disabled. Fix this by splitting the video related stuff to a new file. Also rename the function lcd_iomux to setup_iomux_lcd to make the namings aligned with the other iomux functions.

The inclusion of LCD patch into mx51evk breaks the build when CONFIG_VIDEO is disabled. Fix this by splitting the video related stuff to a new file. Also rename the function lcd_iomux to setup_iomux_lcd to make the namings aligned with the other iomux functions.

[U-Boot] [PATCH 1/2] libfdt: Add support for appending the values to a existing property
by Kim Phillips 13 Nov '12

13 Nov '12

From: Minghuan Lian <Minghuan.Lian(a)freescale.com> Some properties may contain multiple values, these values may need to be added to the property respectively. this patch provides this functionality. The main purpose of fdt_append_prop() is to append the values to a existing property, or create a new property if it dose not exist.

Hey. I wrote a utility to boot Marvell SoCs over serial. If that sounds generally useful, would you be so kind to merge git://github.com/dns42/u-boot.git at dns/kwboot-1 If it's missing sth for that to happen, lemme know. Cheers, Daniel
