| * Phy: Check NULL bus case and undetected phy via ofClément Leger2017-09-061-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From 5e87dc2c24051c2cd2985e513c5a825d51d9bb00 Mon Sep 17 00:00:00 2001 From: Clement Leger <clement.leger@kalray.eu> Date: Tue, 5 Sep 2017 10:37:23 +0200 Subject: [PATCH] Phy: Check NULL bus case and undetected phy via of phy_device_connect can be called with NULL miibus for automatic match with the phy described in the device tree. In the case where the phy was not detected for some unknown reason, the next calls will be done with a NULL bus. This will lead to undefined behavior and more probably crashes.

For the former case, | always return true. For the latter case, return true iff the kernel was | built for BE (implying that the BE MMIO accessors do not perform a swap). | Otherwise return false, assuming LE registers. | | LE registers are assumed by default because most existing drivers (libahci, | serial8250, usb) always use readl/writel in the absence of instructions | to the contrary, so that will be our fallback.

These f_multi_opts are of course no | longer valid when we leave the usbgadget command. Luckily we do not use | the data after we left the usbgadget command, so this never has been a | problem. However, f_multi_opts has some allocated members which we can | not free anymore on gadget unregistration because we no longer have the | pointer to them. | | Fix this by adding a release function to struct f_multi_opts.

| * | clk: imx: cpu: don't store the address of a function parameterUwe Kleine-König2017-08-151-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function imx_clk_cpu takes a const char *parent_name as second paramter. The implementation introduced in commit 9a89ed9d281e then uses the address of this function parameter to assign clk.parent_names. This is an address on the stack that is saved in the clk tree and of course this is easily overwritten by later execution paths of barebox. Without this fix the clk_dump command reproducibly crashes on i.MX7 (which is the only SoC that makes use of imx_clk_cpu()).

To support this the syntax for lcd_wiring_mode was extended to include this info. This is an extension compared to the documented bindings, and an extension the kernel does not support (yet). The binding documents that there can be more than one gpio to power on/off the display but current implmentation supports only one gpio. There are no users that requires more than one gpio so this is good enough. The clk name used for hclk differs from device trees and platform data. We could rename the clocl used in platform data but the name "hclk" is not unique. Configure clockname based on configuration method.

Move registration of the GPIO to the driver so we no longer need to duplicate this for each board. As an intended side-effect there is no longer any references to platform_data outside atmel_lcdc_register() so remove it from struct atmel_lcdfb_info The implementation assumes that GPIO=0 is the same as no power control. This prevents us from using any GPIO=0 for power control, but this is not considered a problem for current users. Future DT users will not have this limitation. This commit include a fix so we will actually power down if requested. Previously this was hardcoded to ON.
