From 3b2d81766fd9c957a9fcfe997ff3d692e9981c98 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Tue, 16 Jun 2020 10:32:29 +0100 Subject: sd: sdhci: Implement basic vendor specific register support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Linux kernel's IMX code now uses vendor specific commands. This results in endless warnings when booting the Linux kernel. sdhci-esdhc-imx 2194000.usdhc: esdhc_wait_for_card_clock_gate_off: card clock still not gate off in 100us!. Implement support for the vendor specific command implemented in IMX hardware to be able to avoid this warning.
