Hello,
This is an updated DWC2 related part of initial patchset posted here:
https://lkml.org/lkml/2015/8/21/306
Only DWC2 related patches have been modified since the initial
submission.
Changelog:
v3:
- rebased onto latest 'testing/next' from Felipe Balbi (includes
s3c_hsotg -> dwc2 rename)
v2:
- moved setting of ll_hw_enabled flag to enable/disable functions,
as suggested by John Youn
- moved setting of phy width to dwc2_lowlevel_init function
Marek Szyprowski (4):
usb: dwc2: remove double call to dwc2_hsotg_of_probe
usb: dwc2: remove non-functional clock gating
usb: dwc2: fix unbalanced phy control
usb: dwc2: refactor common low-level hw code to platform.c

All of them must be enabled/activated to properly initialize and operate. This was initially handled in s3c-hsotg driver, which has been converted to 'gadget' part of dwc2 driver. Unfortunately, not all of this code got moved to common platform code, what resulted in accessing DWC2 registers without enabling low-level hardware resources. This fails for example on Exynos SoCs. This patch moves all the code for managing those resources to common platform.c file and provides convenient wrappers for controlling them.

* [PATCH v4 4/4] usb: dwc2: refactor common low-level hw code to platform.c 2015-10-01 15:59 ` Felipe Balbi @ 2015-10-02 7:45 ` Marek Szyprowski 2015-10-05 22:26 ` John Youn 0 siblings, 1 reply; 22+ messages in thread From: Marek Szyprowski @ 2015-10-02 7:45 UTC (permalink / raw) To: linux-usb, linux-kernel, linux-samsung-soc Cc: Marek Szyprowski, Robert Baldyga, John Youn, Krzysztof Kozlowski, Bartlomiej Zolnierkiewicz DWC2 module on some platforms needs three additional hardware resources: phy controller, clock and power supply. All of them must be enabled/activated to properly initialize and operate. This was initially handled in s3c-hsotg driver, which has been converted to 'gadget' part of dwc2 driver. Unfortunately, not all of this code got moved to common platform code, what resulted in accessing DWC2 registers without enabling low-level hardware resources. This fails for example on Exynos SoCs. This patch moves all the code for managing those resources to common platform.c file and provides convenient wrappers for controlling them. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> --- Changelog: v4: - fixed broken conditional compilation and adjusted comments in dwc2_hsotg structure documentation v3: - rebased onto latest 'testing/next' from Felipe Balbi (includes s3c_hsotg -> dwc2 rename) v2: - moved setting of ll_hw_enabled flag to enable/disable functions, as suggested by John Youn - moved setting of phy width to dwc2_lowlevel_init function --- drivers/usb/dwc2/core.h | 24 +++-- drivers/usb/dwc2/gadget.c | 193 ++++-------------------------------- drivers/usb/dwc2/platform.c | 234 +++++++++++++++++++++++++++++++++++++------- 3 files changed, 228 insertions(+), 223 deletions(-) diff --git a/drivers/usb/dwc2/core.h b/drivers/usb/dwc2/core.h index 3056981..3db5ef2 100644 --- a/drivers/usb/dwc2/core.h +++ b/drivers/usb/dwc2/core.h @@ -578,6 +578,15 @@ struct dwc2_hregs_backup { * - USB_DR_MODE_PERIPHERAL * - USB_DR_MODE_HOST * - USB_DR_MODE_OTG + * @hcd_enabled Host mode sub-driver initialization indicator. + * @gadget_enabled Peripheral mode sub-driver initialization indicator. + * l@l_hw_enabled Status of low-level hardware resources. + * @phy: The otg phy transceiver structure for phy control. + * @uphy: The otg phy transceiver structure for old USB phy control. + * @plat: The platform specific configuration data.

All of them must be enabled/activated to properly initialize and operate. This was initially handled in s3c-hsotg driver, which has been converted to 'gadget' part of dwc2 driver. Unfortunately, not all of this code got moved to common platform code, what resulted in accessing DWC2 registers without enabling low-level hardware resources. This fails for example on Exynos SoCs. This patch moves all the code for managing those resources to common platform.c file and provides convenient wrappers for controlling them.

* [PATCH v6 2/2] usb: dwc2: refactor common low-level hw code to platform.c 2015-10-14 6:52 ` [PATCH v6 1/2] usb: dwc2: remove no longer needed init_mutex Marek Szyprowski @ 2015-10-14 6:52 ` Marek Szyprowski 0 siblings, 0 replies; 22+ messages in thread From: Marek Szyprowski @ 2015-10-14 6:52 UTC (permalink / raw) To: linux-usb, linux-kernel, linux-samsung-soc Cc: Marek Szyprowski, Robert Baldyga, John Youn, Krzysztof Kozlowski, Bartlomiej Zolnierkiewicz DWC2 module on some platforms needs three additional hardware resources: phy controller, clock and power supply. All of them must be enabled/activated to properly initialize and operate. This was initially handled in s3c-hsotg driver, which has been converted to 'gadget' part of dwc2 driver. Unfortunately, not all of this code got moved to common platform code, what resulted in accessing DWC2 registers without enabling low-level hardware resources. This fails for example on Exynos SoCs. This patch moves all the code for managing those resources to common platform.c file and provides convenient wrappers for controlling them.

In > fact, why are you trying to hold a mutex while inside a spinlock ? init_mutex is a leftover from the time, when s3c-hsotg driver didn't implement proper pull up/down control and emulated it by enabling disabling phy. It can be removed now. btw, the possible lockup pointed by John is an interaction of two mutexes, not a case of taking mutex under a spinlock. I will send an updated patch in a few minutes.
