| |
The following series of patches - Add support for GPIO subsystem in main and wakeup domains. - Add voltage regulator device tree nodes and their corresponding pinmux to support power cycle and voltage switch required for UHS-I modes - sets respective tags in sdhci0 node to support higher speeds - remove no-1-8-v tag from sdhci1 node to support UHS-I modes
performance test logs using EXT4 filesystem - For eMMC HS400 speed mode, https://pastebin.ubuntu.com/p/gDxBCwtkt8/ - For SD SDR104 speed mode, https://pastebin.ubuntu.com/p/tHYTn2wxwg/
Changes since v3: - Removed patch (1 in v3). - Rebased and included patches that add support for GPIO from series [1]. - Re-ran the performace tests for SD and eMMC.
Changes since v2: - Added main_gpio0 DT node - Added voltage regulator device tree nodes required to support UHS-I modes
Changes since v1: - squashed the two patches into one - added performance logs for the above mentioned speed modes
