ARM: dts: am335x phytec boards: Fix cd-gpios active level

2019-07-14T06:09:40+00:00

[ Upstream commit 8a0098c05a272c9a68f6885e09755755b612459c ]

Active level of the mmc1 cd gpio needs to be low instead of high.
Fix PCM-953 and phyBOARD-WEGA.

ARM: dts: Drop bogus CLKSEL for timer12 on dra7

2019-07-14T06:09:37+00:00

[ 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: armada-xp-98dx3236: Switch to armada-38x-uart serial node

2019-07-10T07:52:30+00:00

commit 80031361747aec92163464f2ee08870fec33bcb0 upstream.

Switch to the "marvell,armada-38x-uart" driver variant to empty
the UART buffer before writing to the UART_LCR register.

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

2019-06-25T03:34:54+00:00

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

2019-06-25T03:34:54+00:00

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.

ARM: dts: exynos: Always enable necessary APIO_1V8 and ABB_1V8 regulators on Arndale Octa

2019-06-15T09:53:05+00:00

[ Upstream commit 5ab99cf7d5e96e3b727c30e7a8524c976bd3723d ]

The PVDD_APIO_1V8 (LDO2) and PVDD_ABB_1V8 (LDO8) regulators were turned
off by Linux kernel as unused.  However they supply critical parts of
SoC so they should be always on:

1. PVDD_APIO_1V8 supplies SYS pins (gpx[0-3], PSHOLD), HDMI level shift,
   RTC, VDD1_12 (DRAM internal 1.8 V logic), pull-up for PMIC interrupt
   lines, TTL/UARTR level shift, reset pins and SW-TACT1 button.
   It also supplies unused blocks like VDDQ_SRAM (for SROM controller) and
   VDDQ_GPIO (gpm7, gpy7).
   The LDO2 cannot be turned off (S2MPS11 keeps it on anyway) so
   marking it "always-on" only reflects its real status.

2. PVDD_ABB_1V8 supplies Adaptive Body Bias Generator for ARM cores,
   memory and Mali (G3D).

ARM: dts: imx6qdl: Specify IMX6QDL_CLK_IPG as "ipg" clock to SDMA

2019-06-15T09:53:02+00:00

[ Upstream commit b14c872eebc501b9640b04f4a152df51d6eaf2fc ]

Since 25aaa75df1e6 SDMA driver uses clock rates of "ipg" and "ahb"
clock to determine if it needs to configure the IP block as operating
at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both
clocks as IMX6QDL_CLK_SDMA results in driver incorrectly thinking that
ratio is 1:1 which results in broken SDMA funtionality(this at least
breaks RAVE SP serdev driver on RDU2). Fix the code to specify
IMX6QDL_CLK_IPG as "ipg" clock for SDMA, to avoid detecting incorrect
clock ratio.
