Changes in v13:
- remove state_dat1 related description in mtk-sd.yaml
- move device_init_wakeup() to probe stage
- remove redundancy SDC_CFG_SDIOIDE bit control in msdc_runtime_suspend()
- replace SDC_CFG_SDIOIDE control with __msdc_enable_sdio_irq() function to
disable sdio irq when sdio_irq_claimed() return true in msdc_runtime_resume()
- restore to use pm_runtime_force_resume|suspend(), to avoid go out directly
in force resume, bump up runtime PM usage counter before force suspend.
Changes in v12:
- assign NULL to pins_eint directly instead of using kfree()
Changes in v11:
- remove '_irq' suffix in interrupts-names property
- fix yaml example build error
- refactor msdc_enable_sdio_irq(), free pins_eint if async irq is not supported
Changes in v10:
- add sample node for SDIO host which support wakeup interrupt in yaml
- skip MMC_PM_WAKE_SDIO_IRQ check before enable SDIO async interrupt
- add MMC_PM_KEEP_POWER check before SDIO eint pinstate parsing
- use dev_pm_set_dedicated_wake_irq_reverse() to correct irq control sequence
- set dedicated irq in msdc_enable_sdio_irq() rather than msdc_drv_probe()
- remove unnecessary wake irq control, rpm/dpm system shall manage that
- move wake irq/msdc irq control back to system suspend phase, use rpm_suspend
and rpm_resume to ensure irq control sequence:
disable msdc irq -> enable wake irq -> disable wake irq -> enable msdc irq
- simplify variables, check pins_eint to know whether wakeup settings are managed
Changes in v9:
- remove pinctrl "state_dat1"
Changes in v8:
- remove maxItems property under pinctrl-names property
Changes in v7:
- add device_init_wakeup() to register SDIO host as wakeup source
Changes in v6:
- abandon cap-sdio-async-irq flag, use wakeup-source flag instead
- extend interrupts and pinctrls in mediatek mmc host controller DT documents
- add mmc_card_enable_async_irq() to access enable_async_irq flag
- simplify wakeup irq implementation with dedicate wake up irq related interface
Changes in v5:
- resort variables to reversed xmas tree order
- restore old copyright year range and add current year back
Changes in v4:
- add MMC_CAP2_SDIO_ASYNC_IRQ judge before lookup eint pinctrl
- replace spin_lock_irqsave() variant with spin_lock() in eint irq handler
Changes in v3:
- correct abbreviations with capital letters in commit message
- replace copyright year with 2022 in mtk-sd.c
- remove unnessary pointer casting
- adjust variable order to reversed xmas tree
- remove a redundant blank line
- refine if statement, following standard pattern
Changes in v2:
- change flag name from 'cap-sdio-async-int' to 'cap-sdio-async-irq'
- change corresponding macro names from xxx_INT to xxx_IRQ
- resort new member in msdc_host structure
- refine function msdc_request_dat1_eint_irq()
- rename msdc_{suspend,resume} function names, add suffix '_noirq'
- add MMC_CAP2_NO_SDIO judgement before parse eint related pin setting
