Subject: [PATCH v6 0/3] J7200: Add support for GPIO and higher speed modes in MMCSD subsystems
Date: Fri, 19 Mar 2021 09:14:18 +0530 [thread overview]
Message-ID: <20210319034422.17630-1-a-govindraju@ti.com> (raw)
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 v5:
- Corrected the link in patch 3 as it broken.
- Added the version number for the references used in patch 3.
- picked up reviewed-by from gyrgorii for patches 1 and 2.
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
