| Subject | [PATCH 0/2] mmc: sdhci-pci: Use ACPI to set max frequency of sdio host |
| Message-ID | <sG5SN-7Cz-7@gated-at.bofh.it> |
On some boards, max SDIO frequency is limited by trace lengths and other layout
choices. We would like a way to specify this limitation so the driver can
behave accordingly.
This patch set assumes that the limitation has been reported in an ACPI table
which the driver can check to get the max frequency.
The first patch creates a PCI ID and support for the Intel byt sdio where NI is
the subvendor.
The second patch uses the ACPI table to set f_max during the new
ni_byt_sdio_probe_slot.

It makes life easier when reviewing and when I am about to apply patches. Kind regards Uffe

Or does it not matter either way RFC + 1, that would be best. Although it doesn't matter that much. > as long as the history is present? Yes, this is the most important part. Kind regards Uffe
