Hi Alexandru,
From: Alexandru Gagniuc mr.nuke.me@gmail.com Sent: mardi 15 septembre 2020 21:52 To: uboot-stm32@st-md-mailman.stormreply.com; peng.fan@nxp.com Cc: Alexandru Gagniuc mr.nuke.me@gmail.com; Patrick DELAUNAY patrick.delaunay@st.com; Patrice CHOTARD patrice.chotard@st.com; u- boot@lists.denx.de Subject: [PATCH 1/2] mmc: mmc_of_parse: Enable 52 MHz support with "cap- mmc-highspeed" Importance: High
"cap-mmc-highspeed" enables support for 26 MHz MMC, but there is no additional flag to enable 52 MHz MMC. In Linux. "cap-mmc-highspeed" is used for MMC HS at both 26MHz and 52MHz.
Use the same approach and enable MMC_CAP(MMC_HS_52) host capability when "cap-mmc-highspeed" is found in the devicetree. In the event an MMC card doesn't support 52 MHz, it will be clocked at a speed based on its EXT CSD, even on 52 MHz host controllers
