ARM: dts: gemini: Set DIR-685 SPI CS as active low

2019-07-26T07:13:02Z

commit f90b8fda3a9d72a9422ea80ae95843697f94ea4a upstream. The SPI to the display on the DIR-685 is active low, we were just saved by the SPI library enforcing active low on everything before, so set it as active low to avoid ambiguity.

ARM: dts: meson8b: fix the operating voltage of the Mali GPU

2019-07-21T07:01:53Z

[ Upstream commit 26d65140e92a626e39c73c9abf769fd174bf5076 ] Amlogic's vendor kernel defines an OPP for the GPU on Meson8b boards with a voltage of 1.15V. It turns out that the vendor kernel relies on the bootloader to set up the voltage. The bootloader however sets a fixed voltage of 1.10V. Amlogic's patched u-boot sources (uboot-2015-01-15-23a3562521) confirm this: $ grep -oiE "VDD(EE|AO)_VOLTAGE[ ]+[0-9]+" board/amlogic/configs/m8b_* board/amlogic/configs/m8b_m100_v1.h:VDDAO_VOLTAGE 1100 board/amlogic/configs/m8b_m101_v1.h:VDDAO_VOLTAGE 1100 board/amlogic/configs/m8b_m102_v1.h:VDDAO_VOLTAGE 1100 board/amlogic/configs/m8b_m200_v1.h:VDDAO_VOLTAGE 1100 board/amlogic/configs/m8b_m201_v1.h:VDDEE_VOLTAGE 1100 board/amlogic/configs/m8b_m201_v1.h:VDDEE_VOLTAGE 1100 board/amlogic/configs/m8b_m202_v1.h:VDDEE_VOLTAGE 1100 Another hint at this is the VDDEE voltage on the EC-100 and Odroid-C1 boards. The VDDEE regulator supplies the Mali GPU. It's basically a copy of the VCCK (CPU supply) which means it's limited to 0.86V to 1.14V. Update the operating voltage of the Mali GPU on Meson8b to 1.10V so it matches with what the vendor u-boot sets.

ARM: dts: meson8: fix GPU interrupts and drop an undocumented property

2019-07-21T07:01:53Z

[ Upstream commit 01dfdd7b4693496854ac92d1ebfb18d7b108f777 ] The interrupts in Amlogic's vendor kernel sources are all contiguous. There are two typos leading to pp2 and pp4 as well as ppmmu2 and ppmmu4 incorrectly sharing the same interrupt line. Fix this by using interrupt 170 for pp2 and 171 for ppmmu2. Also drop the undocumented "switch-delay" which is a left-over from my experiments with an early lima kernel driver when it was still out-of-tree and required this property on Amlogic SoCs.

ARM: dts: Drop bogus CLKSEL for timer12 on dra7

2019-07-14T06:09:37Z

[ Upstream commit 34f61de87017aff3c8306280d196dddb1e168a88 ] There is no CLKSEL for timer12 on dra7 unlike for timer1. This causes issues on booting the device that Tomi noticed if DEBUG_SLAB is enabled and the clkctrl clock does not properly handle non-existing clock. Let's drop the bogus CLKSEL clock, the clkctrl clock handling gets fixed separately.

ARM: dts: am57xx-idk: Remove support for voltage switching for SD card

2019-06-25T03:34:54Z

commit 88a748419b84187fd1da05637b8e5928b04a1e06 upstream. If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Since am571x-, am572x- and am574x-idk don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz).

ARM: dts: dra76x: Update MMC2_HS200_MANUAL1 iodelay values

2019-06-25T03:34:54Z

commit c3c0b70cd3f801bded7a548198ee1c9851a0ca82 upstream. Update the MMC2_HS200_MANUAL1 iodelay values to match with the latest dra76x data manual[1]. The new iodelay values will have better marginality and should prevent issues in corner cases. Also this particular pinctrl-array is using spaces instead of tabs for spacing between the values and the comments. Fix this as well.
