2019-11-04net: of_get_phy_mode: Change API to solve int/unit warningsAndrew Lunn1-2/+5
Before this change of_get_phy_mode() returned an enum, phy_interface_t. On error, -ENODEV etc, is returned. If the result of the function is stored in a variable of type phy_interface_t, and the compiler has decided to represent this as an unsigned int, comparision with -ENODEV etc, is a signed vs unsigned comparision. Fix this problem by changing the API. Make the function return an error, or 0 on success, and pass a pointer, of type phy_interface_t, where the phy mode should be stored. v2: Return with *interface set to PHY_INTERFACE_MODE_NA on error. Add error checks to all users of of_get_phy_mode() Fixup a few reverse christmas tree errors Fixup a few slightly malformed reverse christmas trees v3: Fix 0-day reported errors.

deferred If the optional regulator is deferred, we must release some resources. They will be re-allocated when the probe function will be called again.

2017-12-13net: ethernet: arc: fix error handling in emac_rockchip_probeBranislav Radocaj1-3/+7
If clk_set_rate() fails, we should disable clk before return. Found by Linux Driver Verification project (linuxtesting.org). Changes since v2 [1]: * Merged with latest code changes Changes since v1: Update made thanks to David's review, much appreciated David. * Improved inconsistent failure handling of clock rate setting * For completeness of usecase, added arc_emac_probe error handling Signed-off-by: Branislav Radocaj <[email protected]> Signed-off-by: David S.

This patch will make the driver more readability The emac has the error and warnings if you run 'scripts/checkpatch.pl -f --subjective xxx' to check. Let's clean up such trivial details.

2016-01-10net: ethernet: arc: Add support emac for RK3036Xing Zheng1-1/+7
The RK3036's GRFs offset are different with RK3066/RK3188, and need to set mac TX/RX clock before probe emac. Signed-off-by: Xing Zheng <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2016-01-10net: ethernet: arc: Keep emac compatibility for more Rockchip SoCsXing Zheng1-24/+45
On the RK3066/RK3188, there was fixed GRF offset configuration to set emac and fixed DIV2 mac TX/RX clock. So, we need to easily set and fit to other SoCs (RK3036) which maybe have different GRF offset, and need adjust mac TX/RX clock. Signed-off-by: Xing Zheng <[email protected]> Signed-off-by: David S.

2014-09-10net: ethernet: arc: Don't free Rockchip resources before disconnect from phyRomain Perier1-1/+2
Free resources before being disconnected from phy and calling core driver is wrong and should not happen. It avoids a delay of 4-5s caused by the timeout of phy_disconnect(). Signed-off-by: Romain Perier <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2014-09-09ethernet: arc: Add support for Rockchip SoC layer device tree bindingsRomain Perier1-0/+228
This patch defines a platform glue layer for Rockchip SoCs which support arc-emac driver. It ensures that regulator for the rmii is on before trying to connect to the ethernet controller. It applies right speed and mode changes to the grf when ethernet settings change. Signed-off-by: Romain Perier <[email protected]> Signed-off-by: David S. Miller <[email protected]>
