mmc->f_max will be overwritten again if host->clk_mul enabled.
And you did not do sanity check if f_max from device tree is valid.

It is a feature implemented by MMC core that re-try a slower clock
when enumerate fails.
See:
drivers/mmc/core/core.c
mmc_claim_host(host);
for (i = 0; i < ARRAY_SIZE(freqs); i++) {
if (!mmc_rescan_t

Freescale does not provide Broadcom driver currently.
It might provide it for MX7D release in the future due to MX7D SDB board
integrated a Broadcom WiFi chip.
But it depends on whether the SLA signed with Broadcom can be ready

This can be usefully when clock core wants to enable/disable clocks.
Then we don't have to convert the struct clk_core to struct clk to call

The only thing __clk_enable/__clk_disable does is NULL pointer checking
of clk except calling clk_core_{enable|disable} which is already handled
by clk_core_{enable|disable}.
So remove this unneeded function.

Chris,
Can you pick this one?
IMX also needs this quirk for imx6q/dl since it can not meet HS200
timing requirement.
David,
Is the unkonwn hw issue in your patch #2
I tested that Chris tree does not have problem.
It's caused by IMX tree updates.
Chris,
Is the way Shawn suggested OK for you?

You need improve the patch title a bit, like:
mmc: sdhci: avoid needless loop for handle SDIO interrupts in sdhci_irq
Otherwise,

I also noticed this issue.
Your fix looks correct to me.
But as following community working way, you need send out patches formerly,
not attach a diff file.
You can refer to 'git send-email' or try with gmail.
BTW, please enrich your patch commit message.
Regards
Dong

command line way as i did in this patch.
We probably may would rather using add more board dts way if can not accept
this patch series.
I already replied that concern in last mail, can you help check it and provi
