arm64: dts: allwinner: a64: Add A64 OlinuXino board (with eMMC) A64 OLinuXino board from Olimex has three variants with onboard eMMC: A64-OLinuXino-1Ge16GW, A64-OLinuXino-1Ge4GW and A64-OLinuXino-2Ge8G-IND. In addition, there are two variants without eMMC. One without eMMC and one with SPI flash. This suggests the need for separate device tree for the three eMMC variants. This patch has been tested on A64-OLinuXino-1Ge16GW with Linux 5.0 from Debain. Basic benchmarks using Flexible IO Tester show reasonable performance from the eMMC. eMMC - Random Write: 21.3MiB/s eMMC - Sequential Write: 68.2MiB/s SD Card - Random Write: 1690KiB/s SD Card - Sequential Write: 11.0MiB/s Changes: v3: Separate dts for eMMC variants v2: Fix descriptions for VCC and VCCQ Link: https://github.com/armbian/build/commit/174953de1eb09e6aa1ef7075066b573dba625398 Signed-off-by: Martin Ayotte <martinayotte@gmail.com> [sunil@medhas.org Fix descriptions for VCC and VCCQ, separate dts for eMMC] Signed-off-by: Sunil Mohan Adapa <sunil@medhas.org> Tested-by: Sunil Mohan Adapa <sunil@medhas.org> Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>

arm64: dts: allwinner: a64: olinuxino: Fix eMMC supply regulator A64-OLinuXino-eMMC uses 1.8V for eMMC supply. This is done via a triple jumper, which sets VCC-PL to either 1.8V or 3.3V. This setting is different for boards with and without eMMC. This is not a big issue for DDR52 mode, however the eMMC will not work in HS200/HS400, since these modes explicitly requires 1.8V.

arm64: dts: allwinner: a64: olinuxino: Add bank supply regulators Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL. This patch adds regulators for them to the pinctrl node. Exception is PL which is used by the RSB bus. To avoid circular dependencies, VCC-PL is omitted. On boards with eMMC, VCC-PC is supplied by ELDO1, instead of DCDC1.
