Signed-off-by: Ben Chuang Signed-off-by: AKASHI Takahiro Signed-off-by: Victor Shih --- Updates in V14: - Use mmc_card_uhs2() to stead sdhci_uhs2_mode() in the sdhci_uhs2_dump_regs(). Updates in V7: - Use sdhci_uhs2_mode() to simplify code. Updates in V6: - Remove unnecessary code. --- drivers/mmc/host/sdhci-uhs2.c | 30 ++++++++++++++++++++++++++++++ drivers/mmc/host/sdhci-uhs2.h | 4 ++++ drivers/mmc/host/sdhci.c | 3 +++ drivers/mmc/host/sdhci.h | 1 + 4 files changed, 38 insertions(+) diff --git a/drivers/mmc/host/sdhci-uhs2.c b/drivers/mmc/host/sdhci-uhs2.c index 608f8ad5aaed..9cb0f1b2a37d 100644 --- a/drivers/mmc/host/sdhci-uhs2.c +++ b/drivers/mmc/host/sdhci-uhs2.c @@ -18,6 +18,36 @@ #define DRIVER_NAME "sdhci_uhs2" #define DBG(f, x...) \ pr_debug(DRIVER_NAME " [%s()]: " f, __func__, ## x) +#define SDHCI_UHS2_DUMP(f, x...) \ + pr_err("%s: " DRIVER_NAME ": " f, mmc_hostname(host->mmc), ## x) + +void sdhci_uhs2_dump_regs(struct sdhci_host *host) +{ + if (!(mmc_card_uhs2(host->mmc))) + return; + + SDHCI_UHS2_DUMP("==================== UHS2 ==================\n"); + SDHCI_UHS2_DUMP("Blk Size: 0x%08x | Blk Cnt: 0x%08x\n", + sdhci_readw(host, SDHCI_UHS2_BLOCK_SIZE), + sdhci_readl(host, SDHCI_UHS2_BLOCK_COUNT)); + SDHCI_UHS2_DUMP("Cmd: 0x%08x | Trn mode: 0x%08x\n", + sdhci_readw(host, SDHCI_UHS2_CMD), + sdhci_readw(host, SDHCI_UHS2_TRANS_MODE)); + SDHCI_UHS2_DUMP("Int Stat: 0x%08x | Dev Sel : 0x%08x\n", + sdhci_readw(host, SDHCI_UHS2_DEV_INT_STATUS), + sdhci_readb(host, SDHCI_UHS2_DEV_SELECT)); + SDHCI_UHS2_DUMP("Dev Int Code: 0x%08x\n", + sdhci_readb(host, SDHCI_UHS2_DEV_INT_CODE)); + SDHCI_UHS2_DUMP("Reset: 0x%08x | Timer: 0x%08x\n", + sdhci_readw(host, SDHCI_UHS2_SW_RESET), + sdhci_readw(host, SDHCI_UHS2_TIMER_CTRL)); + SDHCI_UHS2_DUMP("ErrInt: 0x%08x | ErrIntEn: 0x%08x\n", + sdhci_readl(host, SDHCI_UHS2_INT_STATUS), + sdhci_readl(host, SDHCI_UHS2_INT_STATUS_ENABLE)); + SDHCI_UHS2_DUMP("ErrSigEn: 0x%08x\n", + sdhci_readl(host, SDHCI_UHS2_INT_SIGNAL_ENABLE)); +} +EXPORT_SYMBOL_GPL(sdhci_uhs2_dump_regs); /*****************************************************************************\ * * diff --git a/drivers/mmc/host/sdhci-uhs2.h b/drivers/mmc/host/sdhci-uhs2.h index e993f41ffb7f..2bfe18d29bca 100644 --- a/drivers/mmc/host/sdhci-uhs2.h +++ b/drivers/mmc/host/sdhci-uhs2.h @@ -174,4 +174,8 @@ #define SDHCI_UHS2_EMBED_CTRL_PTR 0xE6 #define SDHCI_UHS2_VENDOR_PTR 0xE8 +struct sdhci_host; + +void sdhci_uhs2_dump_regs(struct sdhci_host *host); + #endif /* __SDHCI_UHS2_H */ diff --git a/drivers/mmc/host/sdhci.c b/drivers/mmc/host/sdhci.c index 4b91c9e96635..5a5fe3528bb4 100644 --- a/drivers/mmc/host/sdhci.c +++ b/drivers/mmc/host/sdhci.c @@ -110,6 +110,9 @@ void sdhci_dumpregs(struct sdhci_host *host) } } + if (host->ops->dump_uhs2_regs) + host->ops->dump_uhs2_regs(host); + if (host->ops->dump_vendor_regs) host->ops->dump_vendor_regs(host); diff --git a/drivers/mmc/host/sdhci.h b/drivers/mmc/host/sdhci.h index e1013925e91e..66ab90bd4017 100644 --- a/drivers/mmc/host/sdhci.h +++ b/drivers/mmc/host/sdhci.h @@ -719,6 +719,7 @@ struct sdhci_ops { void (*request_done)(struct sdhci_host *host, struct mmc_request *mrq); void (*dump_vendor_regs)(struct sdhci_host *host); + void (*dump_uhs2_regs)(struct sdhci_host *host); }; #ifdef CONFIG_MMC_SDHCI_IO_ACCESSORS
