Subject: [PATCH 06/11] power: supply: qcom_smbx: respect battery charge-term-current-microamp
Date: Thu, 19 Jun 2025 16:55:14 +0200	[thread overview]
Message-ID: <20250619-smb2-smb5-support-v1-6-ac5dec51b6e1@linaro.org> (raw)
In-Reply-To: <20250619-smb2-smb5-support-v1-0-ac5dec51b6e1@linaro.org>

Respect the max current limit set on the battery node, one some devices
this is set conservatively to avoid overheating since they only have a
single charger IC (instead of two in parallel).
