From 219a5d5a975a9e561e801dea6c23e98f0c363683 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sat, 14 Nov 2020 17:37:46 +0000 Subject: [PATCH 01/23] net: sun8i-emac: Allow all RGMII PHY modes So far all GBit users of the sun8i-emac driver were using the "rgmii" PHY mode, even though this turns out to be wrong. It just worked because the PHY driver doesn't do the proper setup (yet). In fact for most boards the "rgmii-id" or "rgmii-txid" PHY modes are the correct ones. To allow the DTs to describe the phy-mode correctly, and to stay compatible with Linux, at least allow those other RGMII modes in the driver. This avoids breakage if mainline DTs will be synced with U-Boot.

This lead to unnecessary calls to the GPIO routines, but also always added a half a second delay to wait for a SATA disk to power up. Many thanks to Peter for pointing this out! Fix this by properly comparing the Kconfig symbols against the empty string. strcmp() would be nicer for this, but GCC does not optimise this away, probably due to our standalone compiler switches.

If size in header is bigger, it will use that value instead. In the process of function rework, also add missing function argument.

This is actually not directly related to the MMC controller IP, but an integration choice, dependent on the SoC this appears in. To avoid becoming trapped with some compatible fallback strings, let's remove the whole struct sunxi_mmc_variant, and replace this with a SoC based choice, which we can derive from the CONFIG_MACH_SUNx_y symbols. This will later simplify H616 support.
