phy: tegra: Convert to use match_string() helper

2018-05-20T16:21:22+00:00

The new helper returns index of the matching string in an array. We are going to use it here. Signed-off-by: Andy Shevchenko Acked-by: Thierry Reding Signed-off-by: Kishon Vijay Abraham I

phy: tegra: remove redundant self assignment of 'map'

2018-02-21T06:24:33+00:00

The assignment of map to itself is redundant and can be removed. Detected with Coccinelle. Signed-off-by: Colin Ian King Signed-off-by: Kishon Vijay Abraham I

phy: tegra: fix device-tree node lookups

2017-12-15T10:30:38+00:00

Fix child-node lookups during probe, which ended up searching the whole device tree depth-first starting at the parents rather than just matching on their children. To make things worse, some parent nodes could end up being being prematurely freed (by tegra_xusb_pad_register()) as of_find_node_by_name() drops a reference to its first argument.

phy: tegra: Handle return value of kasprintf

2017-09-26T11:32:48+00:00

kasprintf() can fail and it's return value must be checked. Signed-off-by: Arvind Yadav Signed-off-by: Kishon Vijay Abraham I

phy: Fix ptr_ret.cocci warnings

2016-11-18T12:49:16+00:00

Use PTR_ERR_OR_ZERO rather than if(IS_ERR(...)) + PTR_ERR. Generated by: scripts/coccinelle/api/ptr_ret.cocci Signed-off-by: Vivek Gautam Cc: Kishon Vijay Abraham I Signed-off-by: Kishon Vijay Abraham I

phy: tegra: mark tegra_xusb_lane_lookup_function() static

2016-09-10T11:18:35+00:00

We get 1 warning when building kernel with W=1: drivers/phy/tegra/xusb.c:104:5: warning: no previous prototype for 'tegra_xusb_lane_lookup_function' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'. Signed-off-by: Baoyou Xie Acked-by: Arnd Bergmann Acked-by: Thierry Reding Signed-off-by: Kishon Vijay Abraham I

phy: tegra: add missing header dependencies

2016-09-10T11:18:34+00:00

We get 5 warnings when building kernel with W=1: drivers/phy/tegra/xusb.c:948:27: warning: no previous prototype for 'tegra_xusb_padctl_get' [-Wmissing-prototypes] drivers/phy/tegra/xusb.c:981:6: warning: no previous prototype for 'tegra_xusb_padctl_put' [-Wmissing-prototypes] drivers/phy/tegra/xusb.c:988:5: warning: no previous prototype for 'tegra_xusb_padctl_usb3_save_context' [-Wmissing-prototypes] drivers/phy/tegra/xusb.c:998:5: warning: no previous prototype for 'tegra_xusb_padctl_hsic_set_idle' [-Wmissing-prototypes] drivers/phy/tegra/xusb.c:1008:5: warning: no previous prototype for 'tegra_xusb_padctl_usb3_set_lfps_detect' [-Wmissing-prototypes] In fact, these functions are declared in linux/phy/tegra/xusb.h, so this patch adds missing header dependencies.

phy: Add Tegra XUSB pad controller support

2016-04-29T14:44:47+00:00

Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs. This hardware block used to be exposed as a pin controller, but it turns out that this isn't a good fit. The new driver and DT binding much more accurately describe the hardware and are more flexible in supporting new SoC generations. Acked-by: Kishon Vijay Abraham I Signed-off-by: Thierry Reding
