Hi,

The Lenovo Thinkpad Tablet 10 is a complete disaster under Linux, and
among many problems the SDIO brcmfmac wifi does not work.

I get the following messages in the kernel log:
brcmfmac: brcmf_sdio_drivestrengthinit: No SDIO Drive strength init done
for chip 4324 rev 6 pmurev 17
brcmfmac: brcmf_sdio_htclk: HT Avail timeout (1000000): clkctl 0x50
[repeated]

and the network interface is never created.

I'm running kernel 3.18.4, my brcmfmac43241b4-sdio.bin is identical to
the one in the linux-firmware repository, and I have attached the
brcmfmac43241b4-sdio.txt that I have extracted from the EFI variables.

Any help would be appreciated.

Sébastien
