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 Aswath Govindraju (1): arm64: dts: ti: k3-j7200: Add support for higher speed modes and update delay select values for MMCSD subsystems Faiz Abbas (2): arm64: dts: ti: k3-j7200: Add gpio nodes arm64: dts: ti: k3-j7200-common-proc-board: Disable unused gpio modules .../dts/ti/k3-j7200-common-proc-board.dts | 94 +++++++++++++++++++ arch/arm64/boot/dts/ti/k3-j7200-main.dtsi | 86 ++++++++++++++++- .../boot/dts/ti/k3-j7200-mcu-wakeup.dtsi | 34 +++++++ 3 files changed, 212 insertions(+), 2 deletions(-)
