[RESEND PATCH 0/6] apalis-tk1: updates for v1.1 hw

[marcel at ziswiler.com]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>


This series updates the device tree for the upcoming V1.1 HW samples.
All changes are purely opportunistic meaning they fix stuff which on
older HW was anyway broken so there should be no backwards
compatibility issues.


Marcel Ziswiler (6):
  apalis-tk1: remove spurious new lines
  apalis-tk1: temp alert pull-up
  apalis-tk1: optional displayport hot-plug detect
  apalis-tk1: adjust pin muxing for v1.1 hw
  apalis-tk1: working sd card detect on v1.1 hw
  apalis-tk1: update compatibility comment

[RESEND PATCH 4/6] apalis-tk1: adjust pin muxing for v1.1 hw

[marcel at ziswiler.com]

From: Marcel Ziswiler <marcel.ziswiler@toradex.com>

Configure Apalis MMC1 D6 GPIO on SDMMC3_CLK_LB_IN as reserved function
without any pull-up/down.

Configure GPIO_PV2 as SD1_CD# according to latest V1.1 HW.

Leave SDMMC3_CLK_LB_OUT muxed as SDMMC3 with output driver enabled aka
not tristated and input driver enabled as well as it features some
magic properties even though the external loopback is disabled and the
internal loopback used as per SDMMC_VENDOR_MISC_CNTRL_0 register's
SDMMC_SPARE1 bits being set to 0xfffd according to the TRM! This pin is
now a not-connect on V1.1 HW in order to avoid any interference.
