phy-sun4i-usb: Add support for peripheral-only mode

2016-08-12T09:29:10Z

Use the new of_usb_get_dr_mode_by_phy() function to get the dr_mode from the musb controller node instead of assuming that having an id_det gpio means otg mode, and not having one means host mode. Implement peripheral-only mode by adding a sun4i_usb_phy0_get_id_det helper which looks at the dr_mode, always registering our extcon and always monitoring vbus. If dr_mode is not specified in the dts, do not register phy0 as we then do not know how to treat it. This is actually a good thing as this means we will not be registering phy0 on devices where the otg controller is not enabled in the devicetree.

phy: rockchip-emmc: Wait even longer for the DLL to lock

2016-07-25T08:38:00Z

Two times out of 2000 reboots I ran into the error message "rockchip_emmc_phy_power: dllrdy timeout". Presumably there is some corner case where the DLL just takes a little longer to timeout. Let's give it even more time to handle these corner cases. Signed-off-by: Douglas Anderson Acked-by: Kishon Vijay Abraham I Signed-off-by: Ulf Hansson

phy: rockchip-emmc: Be tolerant to card clock of 0 in power on

2016-07-25T08:38:00Z

It's possible that there are some reasons to turn the PHY on while the clock is 0. In this case we just won't wait for the DLL to lock. This is a bit of a stopgap until we figure out exactly when we're supposed to wait for the DLL to lock and when we're supposed to power cycle the PHY. Note: this patch should help with suspend/resume where the system will try to turn the PHY back on when the clock is 0.

phy: rockchip-emmc: Set phyctrl_frqsel based on card clock

2016-07-25T08:34:20Z

The "phyctrl_frqsel" is described in the Arasan datasheet [1] as "the frequency range of DLL operation". Although the Rockchip variant of this PHY has different ranges than the reference Arasan PHY it appears as if the functionality is similar. We should set this phyctrl field properly. Note: as per Rockchip engineers, apparently the "phyctrl_frqsel" is actually only useful in HS200 / HS400 modes even though the DLL itself it used for some purposes in all modes. See the discussion in the earlier change in this series: ("mmc: sdhci-of-arasan: Always power the PHY off/on when clock changes"). In any case, it shouldn't hurt to set this always. Note that this change should allow boards to run at HS200 / HS400 speed modes while running at 100 MHz or 150 MHz. In fact, running HS400 at 150 MHz (giving 300 MB/s) is the main motivation of this series, since performance is still good but signal integrity problems are less prevelant at 150 MHz.
