net: ethernet: lpc_eth: Handle error for clk_enable

2022-03-16T12:21:45Z

[ Upstream commit 2169b79258c8be803d2595d6456b1e77129fe154 ] As the potential failure of the clk_enable(), it should be better to check it and return error if fails.

net: nxp: lpc_eth.c: avoid hang when bringing interface down

2021-11-02T18:46:14Z

commit ace19b992436a257d9a793672e57abc28fe83e2e upstream. A hard hang is observed whenever the ethernet interface is brought down. If the PHY is stopped before the LPC core block is reset, the SoC will hang. Comparing lpc_eth_close() and lpc_eth_open() I re-arranged the ordering of the functions calls in lpc_eth_close() to reset the hardware before stopping the PHY.

[ Upstream commit 88ec7cb22ddde725ed4ce15991f0bd9dd817fd85 ] Fix to return a negative error code from the error handling case instead of 0, as done elsewhere in this function.

net: lpc_eth: avoid resetting twice

2019-10-13T18:15:25Z

__lpc_eth_shutdown is called after __lpc_eth_reset but it is already calling __lpc_eth_reset. Avoid resetting the IP twice. Signed-off-by: Alexandre Belloni Signed-off-by: David S. Miller

net: lpc-enet: allow compile testing

The lpc-enet driver can now be built on all platforms, so allow compile testing as well. Add one missing header inclusion that is required in some configurations. Link: https://lore.kernel.org/r/20190809144043.476786-11-arnd@arndb.de Signed-off-by: Arnd Bergmann

drivers/net/ethernet/nxp/lpc_eth.c:1316:31-32: WARNING comparing pointer to 0 Compare pointer-typed values to NULL rather than 0 Semantic patch information: This makes an effort to choose between !x and x == NULL. !x is used if it has previously been used with the function used to initialize x. This relies on type information. More type information can be obtained using the option -all_includes and the option -I to specify an include path.

net: lpc-enet: move phy setup into platform code

2019-08-15T19:33:52Z

Setting the phy mode requires touching a platform specific register, which prevents us from building the driver without its header files. Move it into a separate function in arch/arm/mach/lpc32xx to hide the core registers from the network driver.

net: lpc-enet: factor out iram access

2019-08-15T19:33:49Z

The lpc_eth driver uses a platform specific method to find the internal sram. This prevents building it on other machines. Rework to only use one function call and keep the other platform internals where they belong. Ideally this would look up the sram location from DT, but as this is a rarely used driver, I want to keep the modifications to a minimum.
