Changes from v1:
- Patch 1: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- Add NULL checks before calling clk_toggle callback
- Use IS_ENABLED instead of ifdef in tpm_tis_clkrun_toggle()
- Do not call tpm_platform_begin_xfer() and tpm_platform_end_xfer()
from tpm_tis_clkrun_toggle(). Make them static again.
- Patch 2: "tpm_tis: Move ilb_base_addr to tpm_tis_tcg_phy"
- This is a new patch in this series as per suggestion from Jason.
- Is the current implementation ok or I should move the code in tpm_tis_pnp_remove()
and tpm_tis_plat_remove() inside tpm_tis_remove(). That way all the unmapping
can be done in one place, instead of 3 different places now. Also the unmapping
in tpm_tis_init() can be moved to tpm_tis_remove(), since in case of error
tpm_tis_core_init() calls tpm_tis_remove(). Kindly suggest.
Changes from v2:
- Patch 1: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- No changes
- Patch 2: "tpm_tis: Move ilb_base_addr to tpm_tis_tcg_phy"
- Updated is_bsw() function to have the #ifdef CONFIG_X86 check within the function
itself. Also removed the #ifdef CONFIG_X86 from all other places around is_bsw()
