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()
Changes from v3:
- Patch 1: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- Change function name from clk_toggle to clk_enable
- Update the commit message.
- Patch 2: "tpm_tis: Move ilb_base_addr to tpm_tis_tcg_phy"
- No changes
Changes from v4:
- The numbering of patches is now interchanged.
- Patch 1: "tpm_tis: Move ilb_base_addr to tpm_tis_data"
- Had to move ilb_base_addr to tpm_tis_data, from tpm_tis_tcg_phy.
Since the ioremapping of ilb_base_addr had to be done before any TPM access,
hence moved the variable to tpm_tis_data.
- Also move the ioremapping of ilb_base_addr from tpm_tis_init() to
tpm_tis_core_init() i.e. before any TPM access is done.
- Rename marco LPC_CNTRL_REG_OFFSET to LPC_CNTRL_OFFSET
- Update the commit message.
- Patch 2: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- Remove the functions tpm_platform_begin_xfer() and tpm_platform_end_xfer()
- Move the code from these functions to tpm_tis_clkrun_enable().
Changes from v5:
- Patch 1: "tpm_tis: Move ilb_base_addr to tpm_tis_data"
- No changes
- Patch 2: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- Update the commit message.
Changes from v6:
- - Patch 1: "tpm_tis: Move ilb_base_addr to tpm_tis_data"
- No changes
- Patch 2: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- chip->ops was set to NULL in tpm_del_char_device() called from tpm_chip_unregister() in
error/driver exit path. Fix this code. (Suggested by Javier Martinez Canillas and Jason Gunthorpe)
- Add a comment in tpm_tis_clkrun_enable() function.
Changes from v7:
- Patch 1: "tpm_tis: Move ilb_base_addr to tpm_tis_data"
- No changes
- Patch 2: "tpm: Keep CLKRUN enabled throughout the duration of transmit_cmd()"
- Remove unused variables warnings from tpm_tis_pnp_remove() and tpm_tis_plat_remove()
