phy: ralink: mt7621-pci: add sentinel to quirks table

2022-11-16T08:58:17Z

[ Upstream commit 819b885cd886c193782891c4f51bbcab3de119a4 ] With mt7621 soc_dev_attr fixed to register the soc as a device, kernel will experience an oops in soc_device_match_attr This quirk test was introduced in the staging driver in commit 9445ccb3714c ("staging: mt7621-pci-phy: add quirks for 'E2' revision using 'soc_device_attribute'"). The staging driver was removed, and later re-added in commit d87da32372a0 ("phy: ralink: Add PHY driver for MT7621 PCIe PHY") for kernel 5.11 Link: https://lore.kernel.org/lkml/26ebbed1-0fe9-4af9-8466-65f841d0b382@app.fastmail.com Fixes: d87da32372a0 ("phy: ralink: Add PHY driver for MT7621 PCIe PHY") Signed-off-by: John Thomson Acked-by: Sergio Paracuellos Link: https://lore.kernel.org/r/20221104205242.3440388-2-git@johnthomson.fastmail.com.au Signed-off-by: Vinod Koul Signed-off-by: Sasha Levin

phy: samsung: phy-exynos-pcie: sanitize init/power_on callbacks

2022-08-25T09:40:39Z

[ Upstream commit f2812227bb07e2eaee74253f11cea1576945df31 ] The exynos-pcie driver called phy_power_on() before phy_init() for some historical reasons. However the generic PHY framework assumes that the proper sequence is to call phy_init() first, then phy_power_on(). The operations done by both functions should be considered as one action and as such they are called by the exynos-pcie driver (without doing anything between them). The initialization is just a sequence of register writes, which cannot be altered without breaking the hardware operation. To match the generic PHY framework requirement, simply move all register writes to the phy_init()/phy_exit() and drop power_on()/power_off() callbacks. This way the driver will also work with the old (incorrect) PHY initialization call sequence.

[ Upstream commit 32b378a9179ae4db61cfc5d502717214e6cd1e1c ] Error code is overridden, in case the PLL doesn't lock. So, the USB initialization can continue. This leads to a platform freeze. This can be avoided by returning proper error code to avoid USB probe freezing the platform. It also displays proper errors in log.
