[PATCH V2 00/10] arm64: dts: imx8ulp: add more nodes

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

V2:
 Add blank line between property and child node in patch 3
 Move compatible in the beginning in patch 8
 For patch 9, the pinctrl settings are same, because drive strengh only
 has a enable/disable bit.

Add flexspi, cm33, thermal, cpuidle, reserved memory nodes
Enable flexspi, lpi2c7, spi-nor, cm33 for i.MX8ULP-EVK
Set default clock for SDHC

Haibo Chen (3):
  arm64: dts: imx8ulp: add flexspi node
  arm64: dts: imx8ulp-evk: add 100MHz/200MHz pinctrl setting for eMMC
  arm64: dts: imx8ulp-evk: enable lpi2c7 bus

Han Xu (1):

[PATCH V2 02/10] arm64: dts: imx8ulp: set default clock for SDHC

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@nxp.com>

Set default clock rate and parents for SDHC[0,1,2].

The PLL3 PFD2 maximum frequency is 332Mhz, we can't set it to 389Mhz
as USDHC clock parent. Because PLL3 PFD0 is used for NIC, PFD1 is used
for audio, the only choice is PFD3 which can reach to 400Mhz.

USDHC1 and USDHC2 maximum PCC clock rate is 200Mhz in Over Drive mode,
and 100Mhz in Nominal/Low Drive mode, when PTE or PTF is used.

The patch adjusts clock parent to PLL3 PFD3 DIV1 for USDHC0, PLL3
PFD3 DIV2 for USDHC1 and USDHC2. And set the max rate to meet
restrictions.

[PATCH V2 09/10] arm64: dts: imx8ulp-evk: add 100MHz/200MHz pinctrl setting for eMMC

[Peng Fan (OSS)]

From: Haibo Chen <haibo.chen@nxp.com>

Add 100MHz and 200MHz pinctrl setting for eMMC, and enable 8 bit bus mode
to config the eMMC work at HS400ES mode.

Also update to use Standard Drive Strength for USDHC pad to get a better
signal quality per Hardware team suggests.
