2019-11-08hwspinlock: sprd: Remove redundant PM runtime implementationBaolin Wang1-18/+3
Since the hwspinlock core has changed the PM runtime to be optional, thus remove the redundant PM runtime implementation in the Spreadtrum hwlock driver. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-10-04hwspinlock: sprd: Use devm_hwspin_lock_register() to register hwlock controllerBaolin Wang1-5/+3
Use devm_hwspin_lock_register() to register the hwlock controller instead of unregistering the hwlock controller explicitly when removing the device. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-10-04hwspinlock: sprd: Use devm_add_action_or_reset() for calls to clk_disable_unprepare()Baolin Wang1-2/+15
Use devm_add_action_or_reset() for calls to clk_disable_unprepare(), which can simplify the error handling. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-10-04hwspinlock: sprd: Check the return value of clk_prepare_enable()Baolin Wang1-1/+3
We must check the return value of clk_prepare_enable() to make sure the hardware spinlock controller can be enabled successfully, otherwise we should return error. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2019-10-04hwspinlock: sprd: Change to use devm_platform_ioremap_resource()Baolin Wang1-3/+1
Use the new helper that wraps the calls to platform_get_resource() and devm_ioremap_resource() together, which can simpify the code. Signed-off-by: Baolin Wang <baolin.wang@linaro.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2018-05-24hwspinlock: sprd: Switch to SPDX license identifierSuman Anna1-9/+1
Use the appropriate SPDX license identifiers in the Spreadtrum hardware spinlock driver source file and drop the previous boilerplate license text. Cc: Baolin Wang <baolin.wang@spreadtrum.com> Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
2017-05-17hwspinlock: sprd: Add hardware spinlock driverBaolin Wang1-0/+183
The Spreadtrum hardware spinlock device can provide hardware assistance for synchronization between the multiple subsystems. Signed-off-by: Baolin Wang <baolin.wang@spreadtrum.com> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
