Hi Yinbo,
-----Original Message----- From: Yinbo Zhu yinbo.zhu@nxp.com Sent: Thursday, November 22, 2018 4:17 PM To: yorksun@freescale.com; Y.B. LU yangbo.lu@nxp.com; u-boot@lists.denx.de Cc: Yinbo Zhu yinbo.zhu@nxp.com; Xiaobo Xie xiaobo.xie@nxp.com; Chuanhua Han chuanhua.han@nxp.com Subject: [PATCH v1] LS2080ardb: MMC: disable esdhc for dspi
esdhc and dspi have Multiplexed pins, if dspi is enabled and esdhc need to be disabled, This patch is to disable esdhc when rcw config dspi enabled.
[Y.b. Lu] The title and commit message is confusing. From the code changes, I think you can rephrase like,
armv8: ls2080ardb: enable eSDHC pin mux support
CONFIG_FSL_ESDHC_PIN_MUX should be enabled for ls2080ardb whose eSDHC has pin mux with DSPI. This config makes sure esdhc dts node would be fixed with disabled status if DSPI is used, in case of any mmc issue in linux. Also, esdhc should be added in default hwconfig since eSDHC is used in default.

We are moving to TFA boot flow. Please consider to detect the pin mux at runtime.
