Since the EMMC clock was changed from 200Mhz to 175Mhz in FIP, there were some warnings introduced, as the frequency values being checked was still wrt 200Mhz in code. Hence, the frequency checks are now updated based on the current 175Mhz EMMC clock changed in FIP.

This commit is a preparation for enabling XUSB SC7 support. It rearranges Tegra210 XUSB PADCTL UPHY initialization sequence, for the following reasons: 1. PLLE hardware power sequencer has to be enabled only after both PEX UPHY PLL and SATA UPHY PLL are initialized. tegra210_uphy_init() -> tegra210_pex_uphy_enable() -> tegra210_sata_uphy_enable() -> tegra210_plle_hw_sequence_start() -> tegra210_aux_mux_lp0_clamp_disable() 2. At cold boot and SC7 exit, the following bits must be cleared after PEX/SATA lanes are out of IDDQ (IDDQ_DISABLE=1). a. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN, b. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN_EARLY c. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_VCORE_DOWN tegra210_pex_uphy_enable() and tegra210_sata_uphy_enable() are in charge of bringing lanes out of IDDQ, and then AUX_MUX_LP0_* bits will be cleared by tegra210_aux_mux_lp0_clamp_disable(). 3. Once UPHY PLL hardware power sequencer is enabled, do not assert reset to PEX/SATA PLLs, otherwise UPHY PLL operation will be broken.

Therefore, this commit moves the programming sequence to tegra210_usb3_phy_power_on().

2021-05-14phy: Allow a NULL phy name for devm_phy_get()Rob Herring
For a single PHY, there's no reason to have a phy-names entry in DT. The DT specific get functions allow for this already, but devm_phy_get() WARNs in this case. Other subsystems also don't warn in their get functions. Let's drop the WARN for DT case in devm_phy_get().

This driver's remove path calls cancel_delayed_work(). However, that function does not wait until the work function finishes. This means that the callback function may still be running after the driver's remove function has finished, which would result in a use-after-free. Fix by calling cancel_delayed_work_sync(), which ensures that the work is properly cancelled, no longer running, and unable to re-schedule itself.
