[v1] IPQ8074 pcie/wcss fixes

[PATCH 1/4] pcie: qcom: Fix the macro PARF_SLV_ADDR_SPACE_SIZE_2_3_3

Posted by Sricharan Ramabadhran 2 years, 7 months ago

PARF_SLV_ADDR_SPACE_SIZE_2_3_3 macro used for IPQ8074
pcie slave addr size was initially set to 0x358, but
was wrongly changed to 0x168 as a part of
'PCI: qcom: Sort and group registers and bitfield definitions'
Fixing it back to right value here.

Without this pcie bring up on IPQ8074 is broken now.

Fixes: 769e49d87b15 ("PCI: qcom: Sort and group registers and bitfield definitions")

Surely not, this commit only moved the definition containing 0x358 up.

   Oops, infact it was the one just below, this one which changed it.

    "PCI: qcom: Remove PCIE20_ prefix from register definitions"

  Will fix this in V2.
