* [Early WIP] Update sunxi-next to kernel 4.17 * Switch Allwinner 32 and 64bit to U-boot 2018.05 * Adjust patched for 4.17.y / sunxi-next - adjust both configurations - removing FAT support from u-boot (breaks if you try to save) Tested those boards: Cubietruck: wlan fails http://ix.io/1fYS USB OK, HDMI yes Bananapi R40: http://ix.io/1fZm USB OK, HDMI yes Lime A64: USB no, HDMI no, wireless buggy, eMMC yes Orangepi prime H5: OK http://ix.io/1fZJ DVFS no Orangepi2e: DVFS OK, HDMI OK, net OK, wifi OK, eMMC ok, http://ix.io/1fZT * Kernel config update, enabling HDMI on CT+ * Trying to fix A64 HDMI but failed. Fixed M64 ethernet instead * Update orangepioneplus.wip * Update orangepioneplus.wip * Fix H6 build process * Add regulator bits for Orangepizero+, thanks to @5kft * add H5 support for optional 1.3v regulator and 1.3GHz operation This patch adds two optional overlays that can be used to: 1) enable the 1.1v/1.3v regulator on boards that provide the necessary compatible H/W support 2) modify the default CPU clock operating table to add new 1.2GHz and 1.3GHz clocks Note that the generated regulator overlay will only support boards whose 1.1v/1.3v regulator is controlled by GPIO PL6. * updates for the NanoPi NEO Plus2 This change introduces a patch that provides two changes for the NanoPi NEO Plus2: * Configure the "cpu0" to use the "vdd_cpux" regulator; this enables the ability to use higher CPU clocks * Correct the configurations of the on-board power and status LEDs * Adjust nightly building and few boards config cleanup

Subject: [PATCH] drm: bridge: Enable workaround in dw_hdmi for v1.32a
|
|
|
|
Allwinner SoCs have dw hdmi controller v1.32a which exhibits same
|
|
magenta line issue as i.MX6Q and i.MX6DL. Enable workaround for it.
|
|
|
|
Allwinner never released any kind of dw hdmi or errata documentation,
|
|
so it is not clear how many iterations need to be executed. One
|
|
iteration seems to be enough.
