| |
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 - Update delay values for various speed modes supported.
test logs - eMMC HS400 speed mode https://pastebin.ubuntu.com/p/xqZt34mRWf/
- SD SDR104 speed mode https://pastebin.ubuntu.com/p/qM2H85SQvX/
- GPIO logs https://pastebin.ubuntu.com/p/7WXdRxxdWz/
Changes since v4: - Added main_i2c0 pinmux required for doing power cycles to MMCSD1 subsystem - Updated delay values for various speed modes supported - Corrected the ti,ngpio property to indicate highest gpio lines that can be accessed. - Reran the performace tests
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
