Subject: [PATCH 09/10] arm64: meson: fix sdio in dts for JetHub D1
|
|
|
|
Fix the dts to match board's reference design:
|
|
- update vddio_boot regulator to 3.3v (Wi-Fi SDIO module)
|
|
- add vccq_1v8 regulator with 1.8v for eMMC SDIO
|
|
|
|
In the first revision of JetHub D1 the vccq_1v8 regulator was 3.3v.
|
|
All installed eMMC modules were tested to work in HS200 mode at 3.3v
|
|
supply voltage. In the next revisions of the board eMMC will be
|
|
powered with 1.8v according to the standard.
|
