[U-Boot] [PATCH v2 0/5] sunxi: video: add DE2 LCD and ANX6345 drivers
by Vasily Khoruzhick 27 Oct '17

27 Oct '17

This series adds drivers that are necessary to get LCD working on Pinebook: - ANX6345 eDP bridge driver that allows to connect eDP panels to SoCs that have parallel LCD interface - DE2 LCD driver for Allwinner A64. Similar hardware is present in V3s and R40, but is not supported by this driver yet. Whole combination (along with PWM driver which is sent in another series) is tested on Pinebook which is based on Allwiner A64 SoC. Please see https://github.com/anarsoul/u-boot-pine64/ if you want to test it.

[U-Boot] [PATCH] net: phy: marvell: Add functions to read PHY's extended registers
by Lukasz Majewski 26 Oct '17

26 Oct '17

This commit allows extended Marvell registers to be read with: foo > mdio rx FEC 3.10 Reading from bus FEC PHY at address 0: 3.16 - 0x1063 foo > mdio wx FEC 3.10 0x1011 The above code changes the way ETH connector LEDs blink.

[U-Boot] [PATCH v5 0/4] Allwinner SimpleFB Kconfig cleanup and DE2 SimpleFB support
by Icenowy Zheng 26 Oct '17

26 Oct '17

This patchset is mainly for Allwinner DE2 HDMI SimpleFB support. The framebuffer initialized by the Allwinner DE2 driver can be passed by to the kernel as simplefb, and this can enable the kernel to display graphics without having full DE2 driver. Add the suppot of simplefb in DE2 code. The code to find a simplefb with sunxi extension and a suitable pipeline is extracted to a new source file in video/sunxi/. An option is added for device tree simplefb, and furtherly other simplefb support code should also be converted to it. The current only user to the CONFIG_VIDEO_DT_SIMPLEFB, Allwinner DE1 legacy video, has already converted to use the Kconfig option in this patchset. A cleanup commit is introduced for this conversion. Icenowy Zheng (4): sunxi: change the DE1 video option to CONFIG_VIDEO_SUNXI video: sunxi: extract simplefb match code to a new file video: add an option for video simplefb via DT sunxi: setup simplefb for Allwinner DE2 arch/arm/mach-sunxi/Kconfig | 31 ++++++++------- drivers/video/Kconfig | 8 ++++ drivers/video/sunxi/Makefile | 4 +- drivers/video/sunxi/simplefb_common.c | 30 +++++++++++++++ drivers/video/sunxi/simplefb_common.h | 22 +++++++++++ drivers/video/sunxi/sunxi_de2.c | 72 +++++++++++++++++++++++++++++++++++ drivers/video/sunxi/sunxi_display.c | 13 +------ include/configs/sunxi-common.h | 9 +---- scripts/config_whitelist.txt | 1 - 9 files changed, 155 insertions(+), 35 deletions(-) create mode 100644 drivers/video/sunxi/simplefb_common.c create mode 100644 drivers/video/sunxi/simplefb_common.h -- 2.13.5

[U-Boot] ZynqMP qspi
by Liam Beguin 24 Oct '17

24 Oct '17

Hi, I'm testing a new Xilinx zynqmp dev board and was not able to probe the qspi with the latest mainline U-Boot. I see that there is a 'zynqmp_qspi' driver in the Xilinx tree [1] but nothing in mainline. After a little digging, I found a thread on the list [2] (and [3]) and was wondering in what state this was now. [1] https://github.com/Xilinx/u-boot-xlnx/blob/master/drivers/spi/zynqmp_qspi.c [2] https://lists.denx.de/pipermail/u-boot/2016-July/261003.html [3] https://lists.denx.de/pipermail/u-boot/2016-November/273650.html Thanks, Liam
